The IntlChar::isUAlphabetic() function is used to check whether the entered value is an Alphabetic Unicode character or not.SyntaxIntlChar::isUAlphabetic(val)Parametersval − A character or integer value encoded as a UTF-8 string.ReturnThe IntlChar::isUAlphabetic() function returns TRUE if val is Alphabetic Unicode Character.ExampleThe following is an example −OutputThe following is the output −NULL bool(true) NULL

The IntlChar::charMirror() functionfind the “mirror-image” character from the entered character.SyntaxIntlChar::charMirror(val)Parametersval − A character or integer value encoded as a UTF-8 string.ReturnThe IntlChar::charMirror() function returns another Unicode code point that may serve as a mirror-image substitute, or codepoint itself if there is no such mapping or codepoint does not have the Bidi_Mirrored property.ExampleThe following is an example −OutputThe following is the output −string(1) "K" string(1) "*" string(1) "{" string(1) "]" string(1) ")"

The IntlChar::isIDStart() function is used to check whether the entered character is permissible since the first character is anidentifier or not.Syntaxbool IntlChar::isIDStart(val)Parametersval − A character or integer value encoded as a UTF-8 string.ReturnThe IntlChar::isIDStart()function returns TRUE if val is an identifier character.ExampleThe following is an example −OutputThe following is the output −NULL bool(false) bool(true)

The IntlChar::isJavaIDPart() function is used to check whether the entered character is permissible in a java identifier character or not.SyntaxIntlChar::isJavaIDPart( val )Parametersval − A character or integer value encoded as a UTF-8 string.ReturnThe IntlChar::isJavaIDPart()function returns TRUE if val is a Java identifier character.ExampleThe following is an example −OutputThe following is the output −bool(true) bool(true) bool(false) NULL

The IntlChar::totitle() function is used to check whether the entered value is a Unicode character titlecase or not.SyntaxIntlChar::totitle(val)Parametersval − A character or integer value encoded as a UTF-8 string.ReturnThe IntlChar::to title() function returns the simple_Titlecase_Mapping of the code point, if any; otherwise the code point itself.ExampleThe following is an example:OutputThe following is the output −string(1) " " NULL NULL string(1) "K"

The IntlChar::forDigit() function displays the character representation of specified digit in the specified radix.SyntaxIntlChar::forDigit(digit,radix )ParametersDigit − A number to convert to a characterRadix − The radix value. Default 10.ReturnThe IntlChar::forDigit() function returns the character representation of specified digit in the specified radix.ExampleThe following is an example −OutputThe following is the output −int(55) int(53) int(48)

The IntlChar::chr() function is used to check whether the entered character is Unicode value or notSyntaxIntlChar::chr( val )Parametersval − A character value encoded as a UTF-8 string.ReturnThe IntlChar::chr() function returns TRUE if the val is a Unicode character.ExampleThe following is an example −OutputThe following is the output −string(1) "A" NULL string(1) "^"

The IntlChar::isJavaSpaceChar() function is used to check whether the entered value is a space character or not according to Java conventions.SyntaxIntlChar::isJavaSpaceChar(val)Parametersval − A character value encoded as a UTF-8 string.ReturnThe IntlChar::isJavaSpaceChar()function returns TRUE of val is a space character according to Java conventions.ExampleThe following is an example −OutputThe following is the output −NULL bool(false) bool(true) bool(false) NULL

The IntlChar::isJavaIDStart() function is used to check whether the entered character is permissible since the first character is a java identifier or not.SyntaxIntlChar::isJavaIDStart(val)Parametersval − A character or integer value encoded as a UTF-8 string.ReturnThe IntlChar::isJavaIDStart() function returns TRUE if the val begins withJava identifier character.ExampleThe following is an example −OutputThe following is the output −bool(true) bool(true)ExampleLet us see another example −OutputThe following is the output −NULL bool(true) NULL NULL

The IntlChar::ord()function is used to return the Unicode code point value of the entered character.Syntaxint IntlChar::ord( char_unicode )Parameterschar_unicode − A Unicode CharacterReturnThe IntlChar::ord()function returns theUnicode value as an integer.ExampleThe following is an example −OutputThe following is the output −int(72) int(57)ExampleLet us see another example −OutputThe following is the output −int(37) NULL
